ERIK rimenunnnmosson, or 03151330, swnnnn MEANS FOR FIXING THE BLADES OF SGYTI-IES TO THE SN'ATHS Application filed December 4,1929, Serial No. 411,639, and in Sweden J u 23.1929.

This invention relates to a simple and reliable device for fixing the blade of scythes and like to the snath. According to the invention the tongue oi the blade is slid into a turnable holder provided on the'snath or into a mounting in such a position that the tongue, as the blade is swunginto its operative position on the snath is jammed by means of a coupling device comprising for instance a notch or a groove provided in the tongue and a projection or flange provided in the holder or the mounting. The blade is locked in the said position by a bolt or catching device of suitable construction.

The invention is illustrated in the accompanying drawings. Fig. 1 shows in a side view a blade, the tongue of which is provided with a notch for the connecting of the blade with the snath in accordance with this invention. Fig. 2 is a view of a turnable holder for the blade. Figs. 3 and 4 are sections on the lines AB and C-D respectively in Fig. 2-. Fig. 5 is a longitudinal section of a mounting for the holder. Fig. 6 is a section on the line EF in Fig. 5. Fig. 7 shows in a section the mounting and the holder pivoted to the same and also the blade located in the holder and locked in operative position. Fig. 8 shows in a side view the holder located in the mounting and turned to its locked position. Fig. 9 shows in a side view a blade, the tongue of which is provided with a lateral groove adapted to engage a flange provided in the holder or the mounting for fixing the blade. Fig. 10 shows in a side view a holder for the blade shown in Fig. 9. Fig. 11 is a section on the line G-H in Fig. 10. Fig. 12 shows in a longitudinal section a mounting for the said holder. Fig. 13 is a side view of the-mounting partly in section.

Figs. 14: and 15 show in a longitudinal section and in a side view respectively a mounting adapted for the fixing of the blade directly to the same; Fig. 14.115 a section on the line 1-K in Fig. 15. Fig. 16' shows in a perspective view a. blade fixed to a snath by means of the device illustrated in Figs. 14 and 15.

The tongue 1 of the 1 extends longitudinally of the blade.

blade shown in Fig.

notch 3 is provided in the tongue .for the fixing of the blade in a holder 4, shown separately in Figs..2 to 4 inclusive and in combmation with other members as shown in Figs. 7 and 8.

The said holder has a U shaped cross-section "for instance,

one 5 of its flanges having an inner projection6. The opposlte flange 7 1S shorter than the flange 5,

so that the holder is open opposite to the said projection 63, Fig. 4. The holder tapers toward the end at which the projection is located, as seen from Fig. 2. is by means of a pin or rivet.

The holder 4 8 turnably connected to a tongue 9 of a sleeve shaped mounting 10, which is adapted to he slid on the snath and fixed to the same.

slidable in the mounting 10 shown operative bearing against a flange of 11 is a bolt, and held in the position by a spring 12,

the bolt and a pin 13 screwed into the mounting.

For the fixing of the blade to the snath the holder 4. isbrought into an oblique position with relatlon to the mounting with its wider end directed outwards. The

tongue 1 of the blade is slid into the holder in the direction indicated by the arrow, Fig.

2, and with the notch 3 facing the flange 5 provided with the pro ection 6. After the tongue 1 has been slid into the holder,'the

notch 3 is located substantially. opposite to the projection 6. As the blade occupies the said'position it is swung inwards towards the snath, during which operation the holder is turned on the pin 8 and the bolt 11 is kept in its inner posi-. tion by the holder. As the blade occupies its operative position with relation to the snath,

the bolt llis l2 and locks the holder 4,

forced outwards by the spring Figs. 7 and 8.

While the blade is swung into its operative position, the tongue bears aga nst,

tion 6 at its outer, preferably during which operation the back of the flange 7, the notch 3 ofthe tongue 1 engages the projecrounded corner a, so that the tongue is positively drawninto the holder and in consequence of the tapering shape of the tongue and the holder is jammed in the latter. As the blade is in its operative position the holder bears against the mounting and the bolt and besides the tongue bears against the flanges 5 and 7 of the holder 4 ing of the blade isexceedinglysimple. Forv the removing of the blade the bolt 11 is forced inwards by means of a finger and the blade together with the holder then turned outwards, theblade being finallydisengaged from the projection '6:

In the connection device shownin Figs. to 13 inclusive the U-shaped holder 14, tapering toward its one of theblade 18, Fig. 9, adapted to be fixed by means of the device shown in Figs. 10 to .13 inclusive, is provided with a lateral groove 19. The saidgroove 19 is adapted to co-operate with a flange 21 provided in the mounting 16. In order that the said flange 21 may not prevent the holder from being turned, an opening 22 is provided in one of the flangesof the holder.

(iii

- The tongue 20 of the blade 18 is slid into the holder 14 and the blade together with the holder is then turned toward the snath. During the said operation the lateral groove 19 engages by means of its rounded corner I) the rounded corner 6 of the flange 21, which results in the tongue 20 being drawninto the holder 14 and jammed in the same. After the blade has arrived to its operative position, the bolt 17 is forced outwardsand locks the holder. Also in this case the blade is fixed through a single turning of the blade. The disengaging of the blade is easily effected after the bolt 17 has been forced in wardsand the blade swung outwards.

' Figs. 14, 15 and 16 show the most simple form of execution of the invention. In the present form of execution the holder is omit ted and the blade is fixed by the tongue engaging directly the mounting23 fixed tothe snath 28 by screws or the like. The tongue is provided with a lateral groove in accordance with Fig.9, which co-operates w1th a flange 22 provided in the mounting 23. 24 is a bolt providedin the mounting; The mounting 23 has a sleeve shaped part 25, which is located transversely to the mounting and in which the flange 22 is provided. A

lateral opening 26 is provided in the sleeveshaped part 25 leaving a wall 27 at this side of the part. 29 are the nib's ofthesnath 28.

The tongue of the blade is slidinto the sleeve shaped part 25 of mounting 27in the direction indicated by the arrow; in Fig. 15 and is then swung toward the snath. The lat-' eral groove of the tongue then engages the flange 22, while the tongue bears against the wall'27; The tongue is drawn into the sleeve 7 its of the same.

groove in-the holder end, is turnable on a'pin 15 fixed in a mounting'16. The said mount ing is provided with a: bolt 17. The tongue shaped part 25 of the mounting through the co-operation of the lateral groove and the flange 22 and is jammed in the said part. The blade is lockedin its operative position by the bolt 24. g

The invention may evidently, be modified in some respects without exceeding the lim- For instance the projection oriflange of the coupling may be provided onthe tongue of the blade and the notch or ormounting as easily those skilled inthe art.
